Abstract

An experimental investigation of dielectric barrier discharge (DBD) produced in air is
reported in the present paper. The discharge was produced by applying 0?20 kV AC source at
frequency 10?30 kHz. The main objective of the study was to investigate the dependence of
the discharge homogeneity on the frequency of applied source and the geometry of the
electrodes. For this propose, three different types of electrodes were used. The discharge was
systematically investigated on an extended range of electrical parameters using high
frequency digital oscilloscope. Non-thermal nature of the discharge was tested by the
treatment of hydrophobic polymer surface by measuring the change in contact angle with
water drops.

Key words: DBD; electrode geometry; contact angle measurement; surface treatment
